. slipped over the spreading rings are then selves ments constitute the most effective means or carrying the thrust load. I have accordingly illustrated the thrust elements in the drawings in the form of balls and have shown the confronting thrust members formed as ball tracks shaped to properly receive the same. The two thrust members or rings 21 and are spaced apart to bring the ball tracks thereon into proper confronting relatior with the ball tracks on the inner bearing member by spreading means. consisting in the first form of the invention illustrated. of two'rings 25 and 26, split or broken as indicated at 27 in Fig. 2 and of a thickness such that when interposed between opposite edges of the outer bearing member and the thrust rings they will hold the thrust rings in proper spaced apart relation.

In the assemblage or" the bearing thus far described the two-part retainer mounting the load-carrying rollers is first engaged in the channel in the inner bearing member, and the outer bearing member is then the end of the inner bearing member into engagement with the rollers bearing on the track thereon. The thrust rings, like the outer bearing member are also of a size to he slipped endwise over the inner hearing member.

Fig. 2 indicates how one ball-race is first fill'd with balls (see the left hand race in that view) and how by shifting the rings axially the second ball-race can be opened up suiiiciently. as indicated at 28., to admit the balls into the second raceway.

After the balls are in place in the race ways the thrust rings are forced apart and inserted to hold the members in spread apart assembled relation. In the split ring "form of construction this is accomplished by springing the ope as indicated in 2 and then arter spreading" the members apart into final position, engaging the spreading: rings in the spaces then provided at the sides of the outer bearing member and between the bearing member and thrust rings. When thus assembled the tracks occu the nosition illustrated in Fig. 1, with the thrust rings el-d spread apart in proper confronting relation to the thrust shoulders on the inner bearing; member.

The spreading rings may be made of metal or other suitable material and in this form of b ,aring the tit is preferably such to allow the thrust rings to, adjust themmore or less to different relations. For t purpose the outer bearin member 15 is preferably made of slightly larger diameter than the thrust rings so that said thrust rings will not contact the walls of the housing in which the bearing is seated and will. therefore free to adjust themselves.

The spreading rings may be retained in position after the bearing is assembled in in Fig. 5 the spreading rin various ways as by spinning or peening the metal at the edges of the outer bearing memher over the spre: .iing rings at the opposite sides thereof, as indicated at 29 in Fig. 1 the edge portions of the bearing member being in such cases left softer than the worlc ing face of the member to permit this spiniing operation or by any other equally eflective method.

it will be seen from the foregoing that he hearing when assembled constitutes a. simple, compact unit which can be readily handled and which can be mounted by simply applying it to the shaft and housing with which it is intended 'to operate.

In the form of the invention illustrated gs 30 are of continuousor unbroken structure and it is therefore necessary in this form to provide special means for enabling the assemblage of the parts. These special means consist in the illustration in. the provision of slots 31in the faces of the thrust rings 32 and 33 to receive the spreading rings when they have been displaced radially as indicated in Figs. 5 and 7. as more specifically illustrated and described in my oopending application l lo. (53,939.

In Fig. 6 l have illustrated how the spreading rings may be made in halves or egments 3l-3l and 35-35, those segaents being'held in this case as in the preceding case by turning over shoulders 29 at the opposite edges of the outer bearing member 15. Another feature of this form is the utilization of these spreading ring segments as means for retaining the load .carrying rollers in proper engagement with the track on the inn s hearing member, the ring segments being for this pii'rpose extended in far enough. as indicated at 36, to engage with the ends of the rollers and thereby confine them in their proper path.

l ly invention, it will be seen provides bearing, in which theradial and thrust load carrying elements operate independently of each other a d by the employn'ient of the most eliicicnt means for each of these purposes I obtain a hearing which is thoroughly efficient in every respect.

What I claim is:

1. In a bearing of the charactcr set forth, the combination with radially opposed load mpportiug members and rolling elements between said members, the whole thus constituting a radial bearing, of thrust shoulders at the opposite sides of said radial hearing fixed in relation to one of the members of said bearing, facing toward each other and providing opposed thrust receiving ball tracks. concentrically arranged thrust members at the opposite sides of the other member of the radial bearing having ball t 'acks confronting the thrust receiving ball tracks,- balls engaging said ball tracks, spreading meez'e interpesefl hei'ween the mew me eenii:
